Thrust characteristics research on continuous rotating detonation engine

Case Studies in Thermal Engineering, 2023
Detonation combustion can produce pressure enhancement effect, increasing engine thrust. In this paper, a 2D Euler control equation with chemical reaction is used to solve the periodic flow of the detonation wave in a rectangular plane. The combustion of

Effect of combustion chamber diameter size on scramjet rotating detonation under high Mach number flow conditions

AIP Advances, 2023
This study conducted 3D numerical simulations to investigate the impact of combustion chamber diameter on the combustion characteristics of liquid kerosene scramjet rotating detonation under high Mach number flow conditions (Ma6/28 km). After ignition, a

Relativistic simulations of the phase-transition-induced collapse of neutron stars [PDF]

, 2008
An increase in the central density of a neutron star may trigger a phase transition from hadronic matter to deconfined quark matter in the core, causing it to collapse to a more compact hybrid-star configuration.

Reactant Jetting in Unstable Detonation [PDF]

, 2009
We note the common existence of a supersonic jet structure locally embedded within a surrounding transonic flow field in the hitherto unrelated phenomena of unstable gaseous detonation and hypervelocity blunt body shock wave interaction. Extending prior
